coucnnrn WINDOW-SASH.

To all whom it may concern Be it known that I, ALBERT G. HIGGINS, a

citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Concrete VVindow-Sash; and I do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention relates to a concrete window sash, and has for its principal object to provide means for securing glass within the sash.

With the ordinary wooden sash it is customary, when applying the glass to the sash to seat the glass on the stop rails of the sash and hold the same in place by staples, or

other keepers, which are projected into the sash and overlie the edges of the glass. It is, of course, impossible to utilize such staples, or keepers, with a concrete sash, and as a substitute therefor I have provided the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein Figure I is a perspective view of a concrete sash, equipped with my improvements; showing one of the panes sealed to the sash, but with part of the putty removed to illustrate the keepers. Fig. II is a crosssection of one of the side stiles, and a portion of a window pane. Fig. III is a similar view of a center stile. Fig. IV is an enlarged detail perspective of a combined reinforcing and keeper bar. Fig. V is a detail view of part of a modified form of reinforcing and keeper bar.

Referring more in detail to the parts: 1 designates a concrete window sash comprising top, bottom and center rails 2 and side and center stiles 3; with the outside rails and stiles provided with stop rails 5, against which the edges of the glass abut.

Each rail and stile is provided with reinforcing rods 7 one of which is arranged adjacent the surface against which a glass pane abuts; the rod in each outside stile or rail being set inwardly from the stop rail 5 in line with the inner edge of the stile or rail, and a rod in each center stile or rail Specification of Letters Patent.

ranged within the mold within which the.

sash is cast, so that the concrete may be poured over the reinforcement and embed the same therein. Also embedded in the concrete, at the time the sash is formed, is the inner edge of a combined keeper and reinforcing bar 9; the outer edge of which projects beyond the face of the stile or rail and is preferably provided with a bead 10; the embedded inner edge being preferably slit to provide the fingers 12, which are bent oppositely and lie over the outer reinforcing rod 7 to properly space the bar. The bar 9 is also slit adjacent the beaded edge to provide the lips 14: which, when the glass panes are placed against the stiles and rails, may be folded over onto the edges of the glass to hold the same in place until putty may be applied. The sash may be slidably or pivotally mounted in a window frame, and when slidably mounted may be counterweighted in any suitable manner and provided with edge grooves 15 for receiving ribs 16 on the inner faces of the window frame.

The modified form of keeper and reinforcing bar illustrated in Fig. V comprises a bead 10 on its inner, longitudinal edge, which may be embedded in the rail or stile and take the place of one of the reinforcing rods 7 In practising the invention I first mold the window sash in any suitable way, and with the keeper and reinforcing bars applied thereto, so that the inner edges of the bars are embedded in the material and the outer edges projected from the faces of the stiles and rails; the lips 14 being slit, but not spaced, from the body of the bar prior to the assembling of the bar with the window sash. When the glass is to be installed, the panes are applied to the stiles and rails and the lips 14 bent away from the bars and over the edges of the window panes, so that the latter are held in place. After the ears have been applied to the glass, as described, putty 17 is applied to the edges of the glass over the keeper lips in the usual manner.

It is apparent that with this construction, glass may be applied to the sash as readily as to a wooden sash, and that should one of the panes be broken it may be removed and a new one installed without damaging the sash and as quickly as a glass could be replaced in an ordinary Wooden sash.

Having thus described my inventiomwhat I claim as neW therein, and desire to secure by Letters-Patent, is.

1. The combination With a concrete sash, having reinforcing rods therein, of a keeper bar having a lipped free edge embedded in the sash and embracing the reinforcing rod, With the body of the bar exposed and slit to form keeper lips.

2. The combination With a concrete sash, comprising stiles and rails, glass overlying the stiles and rails, bars embedded in the stiles and rails and projecting therefrom, With the projecting portions of the bars slit to form lips, and With said lips folded onto the edges of the glass to retain the same in place,

3. The combination With a concrete sash, comprising a center stile or rail, of a bar havmg a reinforcing portion embedded in the stile or rail and a body portion projected therefrom, glass lying against the stile or rail on opposite sides of the bar, and lips formed in said bar and bent oppositely over the edges of the glass on opposite sides' of said lo'ar.

In testimony whereof I affix my signature in presence of 'tWoWitnes'ses.
